GAS-STOVE.

SPECIFICATION forming part of'Letters Patent No. 368,938, dated August so, 1887.

Application filed November 6, 1886. Serial No. 218,147. (No model.)

To all whom it may concern.'

Be it known that I, JOHN B. FOLEY, acitizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Gas-Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference markedthereon, which form a part of this specication.

My invention relates to certain new and useful improvements in burners for gas-stoves, and has for its object to so construct such a burner that the gas and air admitted thereto shall be thoroughly mingled before combustion, and also to greatly cheapen and improve the lid or plate-of said burner.

That those skilled in the art to which my invention appertains may understand how to make and use the same, I will proceed to describe its construction in detail by reference t0 the accompanying draw/ings, forming a part of this specification, in which- Figure 1 is a plan view; Fig. 2, a similar view, the lid or plate being removed; Fig. 3, a detail view of the under side of the lid, and Fig. 4 a section at the line x x of Fig. 1.

A is the body of the burner, cast in the form of a ring whose cross section is U-shaped, as clearly seen in Fig. 4.. Formed with this body is an inlet, B, through which gas and air are admitted to the combustion-chamber of the burner.

`E is a pin projecting across the inlet in the path of the gasand air, for the purpose presently explained.

C is a lid or cover-plate corresponding in contour to the body A, thus having an open This plate is provided with perforations or holes a, which are beveled from their base inward toward the top, and this has been found to be of great advantage in thecasting of this plate, as it permits the drawing of said holes without difficulty, and obviates the drilling or reaming of the same, which has heretofore been necessary, and consequently increased the cost of production of the plates.

Projecting downward from the plate C and cast integral therewith is a baffle-wall, D, the object of which is to arrest and change the course of the gas and air as they enter the combustion-chamber of the burner, thus distributing them equally to all the perforations.

AThis wallv tapers downward for the obvious purpose of facilitating the casting of the plate. Near both the outside and inside edges of the plate are annular ledges, which are adapted to fit into corresponding grooves in the body, so as 'to form tight joints.

The gas and air in their llow through the inletlpipe pass the pin E, and by it are divided and agitated, and thus thoroughly mingled in their reuniting, and are again agitated and mixed by striking against the baflie-wall D, which momentarily arrests before it divides the current of air and gas before they reach the combustion-chamber, where, whenlighted, they burn, and small jets offlalne issue from the perforations a, in the usual manner. By the burner being open in the center the radiation of its inside walls is utilized in heating the vessel which may be upon the burner,

v through which passes the pin E, securing the said body and the said pipe together and for dividing and mixing the current of gas and air, and of the plate C, having beveled perforations a, and having a baffle-plate, D, cast integral therewith, as and for the purpose set forth. h

' 2. The combination of the body A, having fitted thereto the plate C, having the beveled perforations a, and the baftleplate D, as shown and described.

In testimony whereof I affix my signaturein presence of two witnesses.
